It is introduced that pit and fissure sealant is the most universal and effective to prevent occlusal dental caries. In processing of being applied the pit and fissure sealant, the various kinds of methods are developed to remove organic matters, plaque, microflora and debris in the pit and fissure for increasing the rates of maintain the sealant. Recently, the Er:YAG laser has been used as a new enamel surface treatment method. The purpose of this thesis is compared whether that enamel surface treatment method is superior to other methods or not. 1. 100mJ 5Hz Er:YAG lased enamel surface was similar to acid-etched enamel in SEM evaluation. 2, Mechanical preparation showed decreased microleakage when compared with acid-etching only, but no significant differences in both method. 3. After laser and acid-etching method showed decreased microleakage when compared with acid-etching only.
